Ladies and gentlemen and whoever else, meet the Terminus R808.

Two pods running off a Pi, Raspbian with VH's cgminer. rem26 is working on a simple webconfig package so you won't have to SSH in to configure cgminer.
Note that the Pi is being powered by one pod's auxilary power USB port.

What the port face looks like. We've got USB-A for 5V power out, and a mini USB for control. 12V can be drawn from either a PCIe 6-pin jack or a 2.1/5.5mm barrel jack (for running off a brick). The blue knob is used to adjust core voltage from about 0.63 to 0.80V chip-level, basically the same range as the 2Pac. It can be assembled with a vertical (pictured) or right-angle (front-facing) adjuster.
This guy has an onboard microcontroller that handles fan speed via PWM, detects "ZOMBIE" condition and resets the chips automatically, and will overtemp-shutdown at 80C (to restart mining below 70C).
It's a 100mm square sitting on rubber feet, but there are M3 screwholes at each corner for stacking or mounting in a case.
This miner is built with 8x BM1384 hashing chips. I will be using this form-factor as a standard going forward, so newer versions with better chips will be physically compatible.
For all you flashy-light enthusiasts, it's got a base blue LED and blinks white with returned shares.
